72 Mbit QDR II at 300 MHz — the throughput anchor
The CY7C1512KV18-300BZXC is a 72 Mbit Quad Data Rate (QDR) II synchronous SRAM organized as 4M x 18 bits. The 300 MHz clock rate delivers four data transfers per cycle — two on each clock edge — for a peak read bandwidth of 2.7 Gbytes/s on the 18-bit bus. QDR II architecture separates read and write data ports, eliminating bus-turnaround dead cycles that plague common-I/O SRAMs. The parallel memory interface keeps the data path deterministic for pipelined logic.
Operates from a 1.7V to 1.9V core supply — the 1.8V nominal rail is standard for this density class. The 165-FBGA package (13x15 mm body) uses a 1.0 mm ball pitch. The layout engineer should budget four inner signal layers for fan-out; the core supply decoupling caps sit directly under the BGA on the opposite side of the board.
Board integration and delivery
Supplied in tray format — the standard carrier for BGA devices in volume assembly. The 165-ball FBGA footprint is JEDEC-registered; the solder-ball composition is RoHS-compatible per Infineon's standard material declaration.
